SPINNING RING FOR SPINNING MACHINES Filed Feb. 4, 1939 R. z'je er- Patented June 25, 1940 UNITED PATENT OFFICE 6 Claims.

This invention relates to spinning rings which are particularly adapted for use with bar travelers.

The object of this invention is to provide a spinning'ring for spinning machines which will allow the spinning machine to be run at a very high speed without the traveler throwing outwardly due to the effect of the centrifugal force, and a further object of this invention is to provide the spinning ring with proper lubrication so that the traveler will be free to rotate with the least possible friction, and to only supply lubricant to points around the spinning ring where lubrication is necessary.

The objects are attained by means of the construction which may be briefly described as follows. Carried within a holder, which is part of the spinning ring, is a traveler ring. This ring has upper and lower bearing surfaces on its inner side which are formed'by cutting a groove mid-way of its upper and lower surfaces on the inner side of the ring and by grooving the under side of the ring. For the purpose of lubricating the traveler, there is provided an oil cup integral with the traveler ring, and to conduct the oil from the oil well to the inner side of the traveler ring, I provide a wicking coated with an oilproof covering which is threaded through holes in the traveler ring which extend from the outer side into the groove on the inner side of the ring. The oil-proof coating is removed from the wicking on the parts which are in the groove. The holder for the traveler ring is substantially U-shaped in section, the outer wall being adapted to receive a spring clip which holds the traveler ring in position. The inner wall which extends substantially tothe same height as the traveler ring is spaced a suificient distance from the traveler ring to form an annular groove around which the bar traveler runs.

The invention is hereinafter more fully described and illustrated in the accompany drawing in which Fig. 1 is a plan View of the spinning ring showing a traveler;

Fig. 2 a section on line 2-2 in Fig. 1;

Fig. 3 a section on line 3-3 in Fig. 1;

Fig. 4 a perspective view of the traveler; and

Fig. 5 a section on an enlarged scale through one side of the traveler ring and holder showing also a traveler bar in position as it appears when the device is in operation.

In the drawing like numerals of reference indicate corresponding parts in the difi'erent figures.

The traveler 5 which is of a well known type has a bar 5 which has its ends bent outwardly. Depending from the ends of the bar 5 are legs 2 I. Formed at the lower ends of the legs are hooks 59 which are oiiset inwardly relative to said legs. The spinning ring consists of a traveler ring I which is locked to the holder 2 by means of the spring clip 3. The holder 2 is secured to the traverse bar (not shown) of the spinning machine by meansof the lugs 4.

-The holder 2 is annular in shape having a groove 6 formed therein'to receive the traveler ring i. The outside well i of the holder 2 has formed on its inner side an annular shoulder 8 on which rests the traveler ring I. Towards the upper part of the outside wall 7 on the inner side thereof, is formed an annular groove 9 which is adapted to receive the spring clip 3. The inner wall. so of the holder 2 is inclined outwardly slightly off the perpendicular to prevent the traveler 5 from being pulled out of the spinning ring when doffing, at which time there is usually upward pull on the traveler. The bottom ll of the groove 5 is inclined downwardly towards the centre of the ring to drain surplus oil away from the shoulder 8, on which the traveler ring rests, to a point where it will-do no harm. Formed in the outer wall 7 of the holder 2 is an opening 52 through which passes the handle 3 of the spring clip 3 to facilitate its removal from the groove 8 in the wallv i- I The traveler ring 1 has formed on its inner side a groove l3 which forms an upper bearing surface, it against which the legs 2| of the traveler 5 bear. On the underside of the traveler ring l is formed a groove it. The upper side l5 or" the groove it runs upwardly at an angle, and then turns down abruptly to form an annular shoulder it to contact the shoulder 8 formed in the groove in the holder 2. The junction of the surface l5 of the groove it with the lower part of the surface of thehgroove it forms a lower bearing surface 28 for the hooks 19 of the traveler; Such surface, when the traveler is in position, engages the middle of the hooks l9 substantially directly below the legs 2| of the traveler. g

The inside diameter of the upper bearing surface it is slightly greater than the inside diameter of the lower bearing surface 23. The reason for this is that the lower bearing surface 28 con- 50 tacts the hooks E9 of the traveler 5 and the upper bearing surface it contacts the depending legs 2! of the traveler. Since the hooks [9 of the traveler 5 are offset inwardly relative to the legs 2i and it is desirable that the traveler travels 55 around the traveler ring I with the legs substantially vertical, the inside diameter of the ring at the lower bearing surface 28 must be made smaller in diameter than the upper to compensate for this difierence.

From the construction described it follows that the upper bearing surface engages the legs of the traveler bar well above the centre of gravity of the traveler so that under the centrifugal force generated by the high velocity of the device the traveler bar rocks on the upper bearing surface and tends to press outwardly against the lower bearing surface, thus preventing the jamming effect of the points of the hooks against the inclined surface I5. The traveler bar thus slides freely without any jamming effect against its bearing surfaces.

Formed in the outer side of the traveler ring I is a shoulder 23. The spring clip 3 when engaged in the groove 9 of the wall I contacts the shoulder 23 of the traveler ring I looking it in the holder.

Formed on the outside of the ring I substantially on the same plane as the groove I3 is another groove 23 extending around the circumference of the ring I. Connecting this outer groove 23 with the inner groove I3 are holes 24 which are spaced around the circumference of the ring in groups of two.

Integral with the ring I and the top of which is substantially on the same level as the top of the ring I is an oil well 20 which is formed in the lug 25. Formed in the lug 25 at the same level as the groove 23* on the ring I is a channel 26. Running from the oil well 20 through the channel 26 in the lug 25 is the wicking 21. This wicking 21 is threaded through holes 24 in the ring I into the groove I3 on the inside of the ring I and is threaded back through the next adjacent hole into groove 23 and so on around the ring until the wicking is finally returned to the oil well 20 through the channel 26. The wicking 21 is encased in an oil proof cover or coating except for the parts which extend into the groove I3 on the inside of the traveler ring I. The object of the oil-proof covering on the wicking 21 is to prevent any seepage of oil except at points around the inner side of the ring I where the oil is required.

What I claim is:

1. In a spinning ring adapted to be used with a bar traveler having depending legs and inwardly offset and outwardly and upwardly facing hooks at the lower ends of the legs, the combination of the traveler ring formed with an upper bearing surface within the ring adapted to engage the upper parts of the legs of the bar traveler and with an inwardly and downwardly facing lower bearing surface adapted to engage the middle portions of the hooks of the bar traveler substantially directly beneath the upper parts of the said legs; a holder for said ring; and an inner wall on said holder forming an annular groove between the traveler ring and said wall around which the traveler bar travels.
